XmlReader.ReadContentAsInt Method

Reads the text content at the current position as a 32-bit signed integer.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)

public virtual int ReadContentAsInt()

Return Value

Type: System.Int32
The text content as a 32-bit signed integer.

ExceptionCondition
InvalidCastException

The attempted cast is not valid.

FormatException

The string format is not valid.

This method concatenates text, white space, significant white space, and CDATA sections, and skips any comments or processing instructions. Entity references are automatically resolved.

If the content is typed xsd:integer, the reader returns an unboxed 32-bit signed integer. If the content is not typed xsd:integer, the reader attempts to convert it to a 32-bit signed integer according to the rules defined by the W3C XML Schema Part 2: Datatypes recommendation.
